Installation
Bus structure
•
All devices are connected in a bus structure
(line).
•
In one segment, up to 32 participants can be
switched together.
•
The cable is terminated with resistors at the
beginning and end of a segment.
•
Repeaters (power boosters) must be used
with more than 32 participants in order to
connect the individual segments.
•
Devices with terminated resistor have to be
supplied.
•
We recommend to install the master device
at the end of the segment.
•
In case that the master device with termina-
ted bus resistor will be removed, the bus is
not under operation.
•
In case that slave device with terminated bus
resistor will be removed or is not switched
on, the bus is can be unstable.
•
Devices which have no termination can be
replaced without any interruption of the bus.
